RAILWAY-TRACK.

Specification of Letters Patent.

- described and claimed.

In the drawings, Figure 1 is a perspective view of a metal tie adapted for use in connection with. this invention. Fig. 2 is a crosssection through a portion of the tie, showing the rails in place; and Fig. 3 is a view of a tie of a slightly-modified form.

Railway-tracks need to be so embedded in the ground or in ballast or other foundation as to be incapable of longitudinal or lateral movement, and of the two movements the lateral movement is the more detrimental. Further, the use of metal for ties is desirable on account of its cheapness, rigidity, and permanency.

In the drawings, Fig. 1 shows a metal tie adapted to support rails and to maintain them in place in the desired position upon the road-bed. The tie consists of a bar of metal 1, having two folds 2 2 projecting downwardly therefrom and having the groove 3 between the folds transverse to the body 1. At right angles to these folds and along one or both edges of the body 1 are downwardlyturned flanges 4 and 5, the flanges 4 being turned down from the edges of that portion of the tie between the folds 2 and the flanges 5 being turned down from the side edges of the end portions 6 of the tie outside of the folds 2. In the form of tie shown in Fig. 1 the edges from which the flanges are turned down are in straight lines; but in Fig. 3 these edges are curved lines, as shown at 7 and 8,

. whereby the tie may be made of a piece of sheet metal, say, three-eighths or one-half inch in thickness, with parallel edges, and then the flanges 9 and 10 are turned down from these parallel edges by stretching the metal, substantially as shown in said Fig. 3. In the cavity or groove 3 in the interior of the flange 2 is set a flangeless rail, which has a vertical web 11, that fits in the groove 3 and extends from tie to tie and into the ground between the ties. Upon the top of the web 11 is the head 12 of the usual form of rails. The web 11 of the rail is in many instances bolted in the groove 3 by a suitable bolt 13, passing through the two walls. of the fold 2 and through the web 11 thus fastening the parts together. In some instances, however,

1 this mode of bolting appears to be unnecessary. The bolt-holes 14, Fig. 1, are drilled through the two'sides of the fold 2 in those ties where the bolting is desirable. The deep fold 2 and the flanges 4 and 5 at right angles to said folds rest in the ballast, ground, or foundation for the railway-track and prevent either longitudinal or lateral movement of the ties, thus maintaining the rails in proper position, and the webs 11 of the rai s between the ties also tend to maintain the rails in proper position longitudinally by means of the large surface which would have to be forced laterally through the ground, ballast, or other foundation. In Figs. 1 and 2 also the flanges 4 and 5 of the tie are shown integral with the edges of the folds 2, as stated above, and are turned down between said folds from the bottom of each fold in each direction. In this way the maximum staying of the folds is produced.

What I claim is 1. A railway-track consisting of a series of ties having registering transverse grooves provided with walls, a series of flangeless rails'each consisting of the usual head and a vertical web set in the grooves of the series of ties, and bolts passing through the walls of said grooves and through said web.

2. A railway-track consisting of a series of ties having registering transverse grooves provided with walls, a series of flangeless rails each consistin of the usual head and an integral, vertica web set in the grooves of the series of ties, and bolts passing through the walls of said grooves and through said web.

3. A railway-track consisting of a series of ties having folds therein transverse to the tie, a flange longitudinal to the tie, and a series of rails, each consisting of the usual head and a vertical flange resting in the grooves formed groeves formed by the folds of the series of by the folds of the series of ties. ties. l
